eonline. Luckily, if you've got Keren Craig and Georgina Chapman of Marchesa and Marie Claire senior fashion editor Zanna Roberts Rassi on your side—like Ashley Greene did—you're bound to hit a glam slam.
That is exactly what the Twilight star did on Monday night and all it took was switching up her angelic style to for a grungier glamour.
"I like the idea of going dark, because I usually wear a lot of light, pretty, airy dresses," she explained at her fitting. "I definitely want to something that makes a huge statement since this is the one place you can do it."
So how did she think she looked after trying on the dress? Like a "really dark princess!" Of course, royalty gets the very best accessories, which is why Ashley topped off her look with Christian Louboutin peep-toes and Harry Winston jewels worth an estimated $1 million.
"I don't care if they are competing [with the dress] I'm wearing them!" she joked.
